老師您好:
不好意思又要麻煩你了。
在study note財報分析第318頁,有講到goodwill,內容是說當goodwill impaired時,goodwill is written down on the balance sheet and the consequent loss is recognized on the income statement. In periods after a write-down, ratios such as ROA, ROE will improve because the denominator of each is reduced.
我疑惑的是,雖然分母都減少了,但是分子Net income不是也會減少嗎?
如果兩個同時減少,照理來說ratio應該會降低啊?為何會improve呢?
老師解答,謝謝!
答覆:
你的中文概念指的是商譽減損的「當年度」,因此你的看法是對的。
你所附的最後一句英文,原版的英文為:
In periods after a write-down, ratios such as ROA, ROE, and asset turnover will improve because the denominator of each is reduced.
也就是英文原文的概念是類似ROA、ROE及資產週轉率等比率,會因為每一個比率的分母(資產與權益)減少,而使得商譽減損以後的後來年度之ROA、ROE及資產週轉率會改善。
這裡的英文指的是商譽減損以後的後來年度。
也就是在後來年度,已經減損商譽的資產與權益比未減損商譽前的資產與權益還小。因此,在未來年度的稅後淨利不變之下,ROA、ROE及資產週轉率的分母變小,使得這三個比率變大。
你若比較CFA協會Level 1 2008年的Volume 3 p.221的第四段第三行:
If goodwill is deemed to be impaired, it is charged against income in the current period. This charge reduces current earnings. Assets are also reduced, so some performance measures, such as return on assets (net income divided by average total assets), may actually increase in future periods.(也就是最後三個英文字:in future periods)
你會發現指的都是未來的期間,也就是已經減損商譽以後的下個年度等等…以後的年度。
